淄河源区岩溶地下水可开采资源量评价

为解决淄博市博山区农业、生活供水短缺,合理有效地调蓄利用岩溶地下水资源,针对淄河源区实际所处地质、水文条件及区域水文地质参数或水均衡要素不清等问题,本研究提出在开采性试验结果的基础上,应选用补偿疏干法来合理评价淄河源区岩溶地下水资源量.该方法能够适用淄河源区有较大的岩溶地下水储水空间可供调蓄且雨旱季分明等特点,体现"以丰补歉"思想.运用该方法计算出淄河源区可开采资源量为14 390 m~3/d.结果表明,补偿疏干法来评价岩溶地区地下水资源是适用的,它可以更广泛地适用于含水层分布范围有限,但有较大储存量,地下水补给雨旱季分明的北方地区.

Application of Compensatory-Drainage Method on Evaluation of Karst Groundwater Safety Yield in Zihe Source Area

In order to solve the shortage of agricultural and domestic water supply in Boshan District of Zibo City and rationally regulate and utilize karst groundwater resources, the Compensating-Dewatering method has been proposed to revaluate reasonably the amount of karst groundwater resources in Zihe source area on the basis of the aquifer test results in view of the actual geological and hydrological conditions and the unclear hydrogeological parameters or water balance factors faced. Because, in this method, the characteristic in Zihe River source area has been adapted which has a large Karst groundwater storage space and clear rain and dry seasons, and the thought of "water abundance in rainy season to make up shortage in dry season" been embodied, this method proves effective and the safety yield was calculated to be 14390m3/d. The research shows that the Compensating-Dewatering method is effective to evaluate groundwater resources in Karst areas. It can be also more widely applied to northern areas where aquifer distribution is limited, but the large underground reserves can play a sufficient adjustment role, and groundwater recharge is clear in the rain and dry season. All in all, It will provide a scientific basis for the local government to rationally determine the amount of sustainable groundwater safety yield and to plan and construct an emergency water supply source in Zihe source area.
